'.ro .eLLfWHoM ITMAY ooNeEnNt/A A Be it known that I, N. HQMEAD, ofWaterportfin the county of Orleans, and lState of New York, have invented a new and improved Tire-FraIne Attachment; and I do hereby declaro that theifollowing is a-full,

clear, and exact description thereotvhieh will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication.-

Figure 1 is a vertical section of my'improved machine, taken through the line a: zzz, iig.

Figure 2'is a partial to'p`view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of tirati-ames, so as to make them more con` venient and eifective in operation, and which will enable the wheel to be detachedand turned, when required, 'before the tire can get cold; and it consists in the construction-and combination of the operating parts, as hereinafter more fully described. I p I Avis thewooden framework of th`e machine, which may be made of any desired form, and the top of which .should be protected with a metallic plate or plates, B, to prevent the hot'tire from burning the wood-work of the said frame A.

C is a lever, `the inner end of which is pirated to the eyes of an eye-bolt, D, or other suitable support, attached to the cross-bar a ofthefrgame A. Y Y,

E is a bar, the lowerendof which passes through aud`is `pivoted to the lever C by a pin passing through 'the said lever, and through one oi the `other of the holes formed through the saidlower part of thecsaid bar E,

as shown in iig. 1. Y A Y i Upon one edge of the upper p'art of the bar E isformed a series" of teeth, e', to take hold ofthe slotted cap-plate F, to clamp the` wheel to the` frame A.

-To .the forward part ofthe lever C is attached a. plate, c', the edge of which is formed and projects in such a way as to take hold of the teethV of the ratchet-bar G, attached to theframe A, so as to hold the said lever securely at any point to which it may be lowered, clamping the 'wheel with any desired' firmness.

This construction enables vthe wheel to be detached and turned, when required, almost instantly, before the tire'can become cold. l i

It also enables the operator, by simply bringing the lever e to the same Vnotch of the raellr G,`"to give all the wheels the same dish. Y d

I claim as new, and desire to secure by Letters Patent- The combination of the pivoted lever @adjustable toothed har E, slotted cap-plate F, and toothed bar G, with each other and with the frame A, substantially ashereiu shown and described, and for the'purlpose set forth.
